WHEELED GUN CARRIAGE WITH SPREAD-OUT TRAIL.

Application filed February T 0 all whom it may concern:

Be it known that T, Fnrnnnrorr STOCK, residing at Essen-on-the-Ruhr,Germany, a citizen of the German Empire, have invented a certain new anduseful Improvement in Wheeled Gun Carriages with Spread-Out Trail, ofwhich the followin is a specification.

The present invention relates to wheeled gun carriages with spread outtrail and resides in a novel solution of the problem of making possiblea stable positioning of the gun carriage on uneven ground.

In the accompanying drawing Fig. 1 shows one embodiment of the inventionas a side view, partly in section, of the parts concerned of a guncarriage;

Fig. 2 the corresponding top plan view, partly in section along line 22of Fig. 1, but without gun-barrel, cradle and top carriage;

Fig. 3 a similar view to Fig. 1 of a second embodiment of the inventionand Fig. 4 the corresponding top plan view, partly in section along linel-4c of Fig. 3.

The gun carriage illustrated in Figs. 1 and 2 will first be described.The axle tree A of the gun carriage is provided with two crankedportions offset 180 against each other. On the crank journals (6 and aformed in this manner, and the geometrical axes of which run parallel tothe axis of revolution of the wheels J, are revolubly mounted the tworearwardly diverging trail sides B and B through the intermediary oftwopart slides C, which embrace the journals a a and are slidable inbearings of the trail sides B B Between the trail sides B B areinserted, in the usual manner, links, not shown, for the purpose ofcoupling together the trail ends during transportation of the guncarriage. Between the inner crank arms a of the journals a a see Fig. 2,is revolubly mounted around the axle tree A, a member D. This member isprovided with a socket d Fig. 2, for the vertical pivot 6 Fig. 1, of thetop carriage E, in which the cradle F, carrying the gun barrel, ismounted by means of horizontal trunnions 7. An elevating gear G G Fig.1, having a toothed arc, is inserted between the top carriage E and thecradle F, whilst the top carriage E may be trained relative to themember D by means of a training gear, not shown. The trail sides B B andthe mem- Patented Jan. f3, 1922.

ber Dare provided with extensions 5 and (Z respectively, which arehinged together by means of a pin H.

In consequence of the described arrangement, the following movementswill occur, on unlimbering the gun carriage on ground, where the toursustaining points for the gun carriage, namely, the contact places ofthe wheels J, and the two trail sides B B are not situated in one andthe same plane. As soon as one of the trail sides, B for instance, hasreached the ground, the other trail side B actuated by the preponderenceof the gun carriage lowers itself with regard to the trail side B, sothat the freeend of the extension 6 of the trail side B moves upwards.Simultaneously the axle tree A turns slightly in the wheels J in such adirection, that the crank journal a swings downwards and the crankjournal a upwards. The trail side B with its extension Z2 partakes inthe upward movement of the crank journal {:1}, without losing its holdon the ground. The slides C simultaneously sulter a slight displacementin their guides 6 During this movement of the trail sides B B and theaxle tree A, the member D does, moreover, by means of the pin H, performa slight oscillation around the axle tree in the direction of the arrow:20, Fig. 1.

With regard to the embodiment shown in Figs. 8 and 4, the axle tree A,upon which the trail sides B B and the member D are revolubly mounted,is in this case straight, not cranked; but the extensions 79 of thetrail sides are on the other hand connected with the extension al of themember D, by means of a crank shaft K k 10 the crank journals. k 72 ofwhich are angularly displaced 180 relative to each other. This crankshaft rests revolubly in a bearing of the extension d which is closed bya cover (P. The journals 76 and 70 which are parallel to the axis ofrevolution of the wheels J, are mounted in two-part slides M, which aredisplaceable in guides 79 of the trail side extensions 6 Also with thisarrangement the rear ends of the two trail sides B 1 may adjustthemselves relative to each other at different heights, within certainwide limits. With regard to the operation of this arrangement, it shouldonly be mentioned, that through opposite movement of the two trailsides, a turning of the crank shaft in the bearing (Z d occurs, as wellas an oscillation of the member D around the axle tree A. The slides Msimultaneously execute a displacement in the guides I).

I claim I 1. A wheeled gun carriage having an axle tree and a rearwardlyspread-out trail, comprising two separate trail-sides, and a crankshaftdevice having journals connecting said trail-sides with each other andwith said axle tree; said journals running parallel to the axis ofrevolution of the carriage wheels.

2. A wheeled gun carriage having a gun supporting member and twoseparate trail sides, a straight common journal for said member and saidtrail sides and a crank shaft having journals connecting said trailsides with said member, the axes of said crank shaft journals and ofsaid straight journal all being parallel with the axis of rotation ofthe carriage wheels.

3. A wheeled gun carriage having a gun supporting member and twoseparate trail sides, a straight common journal for said member and saidtrail sides and a crank shaft having journals connecting said trailsides with said member, the axes of said crank shaft journals and ofsaid straight journal all being parallel with the axis of rotation ofthe carriage wheels, and the axis of oscillation of said membercoinciding with the axis of revolution of said wheels.

4; A wheeled gun carriage having a gun supporting member and twoseparate trail sides, a straight common journal for said member and saidtrail sides and a crank shaft having journals connecting said trailsides with said member, the axes of said crank shaft journals and ofsaid straight journal all being parallel with theaxis of rotation of thecarriage wheels, sliding bearings for said crank shaft journals andguideways in the trail sides for said sliding bearings.

5. A wheeled gun carriage having a gun supporting member and twoseparate trail sides, a straight common journal for said member and saidtrail sides and a crank shaft'having journals connecting said trailsides with said member, the axes of said crank shaft journals and ofsaid straight journal all being parallel with the axis of rotation ofthe carriage wheels, sliding'bearings for said crank shaft journals andguideways in the trail sides for said sliding bear-- ings, the journalaround which said member oscillates being in alignment with, andintegralwith the axle tree.
